This document provides an overview of ancient Egypt, beginning with a timeline of important dates. It then summarizes the geography of Egypt and Mesopotamia, noting how the predictable flooding of the Nile river made Egypt suitable for agriculture. Egyptian society was stable for 3000 years due to natural defenses and the river. Key periods of Egyptian history are outlined, along with the development of hieroglyphic writing and the important gods like Osiris, Isis, Horus and Ra. The document analyzes the Palette of Narmer, dating to 3000 BCE, which symbolizes the unification of upper and lower Egypt under King Narmer and the beginning of the dynastic period.

This document provides an abstract and agenda for the "Company of Images" conference being held in London from September 18-20, 2014. The conference will explore how ancient Egyptians populated their imaginary world through material culture from the Middle Kingdom period (2000-1600 BC). Several presentations will analyze objects and imagery from excavations to understand Egyptian conceptions of the afterlife, personal piety, and demons. Other talks will examine representations in funerary art and how technical aspects relate to the functions and meanings of images. The goal of the conference is to better understand how Egyptians combined different images and materials to construct their imaginary universe.
The document discusses the Precambrian-Cambrian boundary, which remains controversial despite ongoing research. Radioactive dating and other stratigraphic methods have advanced our understanding of early Cambrian evolution. Laminated stromatolites from the Precambrian provide fossil evidence, while biosedimentary structures indicate the boundary location. Determining an accurate timeframe for the boundary is difficult as evidence suggests a transition period of 30-50 million years between Ediacaran fauna (620-700 million years ago) and the appearance of trilobites.

- The Pitts River Basin has been inhabited for thousands of years, with archaeological evidence showing changing patterns of human occupation and land use over time.
- Archaeological data from the region exhibits significant variability, with sites ranging widely in age, material culture, and features.
- There are several potential explanations for this variability, including environmental and climatic changes influencing settlement and subsistence patterns, changing technologies, and cultural and social developments among the indigenous populations.
- Thoroughly investigating the archaeological record of the basin and comparing evidence across sites can help archaeologists better understand the human histories of the region
Forensic Archaeology – Mass Disasters.pptxeli2300475
The document discusses natural disasters and forensic archaeology. It covers how forensic anthropologists have helped analyze past disasters and human remains. They have provided insights into deaths from events like Mount Vesuvius' eruption through analyzing vitrified brain matter and burnt remains. Reconstructing skeletons also helps reveal information about people who lived in the past, like a woman in colonial Maryland who may have been poisoned. The document shows how forensic science can help us better understand natural disasters, the people affected, and make improvements for the future.
This document provides a recap of a lecture on the history of architecture and the built environment. It discusses man's early attempts to colonize and personalize space through examples like cave paintings at Lascaux and Bhimbetka Caves in France and India. These early shelters and paintings showed how prehistoric humans started inhabiting spaces and modifying them to suit their needs and beliefs, which included depicting animals they hunted and worshipping supernatural spirits through religious structures like menhirs.
A History of the World in a Dozen ObjectsLynda Balloni
This document provides a summary of 12 objects discussed in a paper about human manipulation throughout world history. The objects range from a 3500 BCE Egyptian clay cattle figurine representing early domestication, to a 1573-1598 Spanish coin representing the age of European imperialism. Common themes discussed are how humans have sought to elevate themselves above other humans and nature, through practices like claiming divine status for rulers, depicting gods as human, and exploiting natural resources and other humans for economic and political gain. The paper argues that since the agricultural revolution, humanity has followed a path of manipulating nature and each other through practices like slavery, colonialism, and economic exploitation, rather than cooperating for collective benefit.

The Creation Museum as
Engaged Orthodoxy
5
Articles in popular media outlets have not only raised awareness about the
$27 million Creation Museum, but such press coverage has also imbued the
venue with important symbolic value. In a sense, the museum functions as a
kind of shorthand—a codeword for conservative Christianity or an emblem
of political divisions within U.S. culture and politics generally.1 Like the
“Great Passion Play” and the other Sacred Projects in Eureka Springs, the
Creation Museum constructs a cultural paradigm fueled by notions of em
battled Christianity and then supplies visitors with a resonant, comforting
encounter that validates their position within that paradigm.
The great majority of articles appeared when the museum opened in
May 2007, but more recent pieces, such as a 2010 piece in Vanity Fair, testify
to people’s ongoing curiosity about the venue.2 In my own experience, the
Creation Museum prompts more questions from friends and colleagues than
any of the other venues I examine in this book. It is not simply the museum’s
antievolution message that fascinates people. Even more compelling is how
the Creation Museum actually conveys that message. By coupling the physi
cal form of a traditional natural history museum with a radical community- •
based agenda, the Creation Museum empowers and gives public voice to a
community that perceives itself as threatened, disenfranchised, and misreP'
resented by mainstream culture. Using performative tactics, the Creation
Museum appropriates both scientific evidence and the natural history mu
seum encounter for the creationist agenda, while simultaneously align111-1’

probably must—employ the kinds of "discriminatory elements” that John
pletcher suggests are “necessarily present in any expression of coinmuni-
ly."' However, because the museum’s performance relies in great part on the
premise that the exhibits simply give visitors “the freedom to see what they
want to see,'"' museum employees refract any allegations of discrimination
back onto traditional natural history museums, most of which "proclaim
an evolutionary, humanistic worldview.", For creationist-visitors who ap
proach the Creation Museum believing that “secularized" science's evolu
tionary narrative has misled and corrupted society, encounters with the mu
seum's space provide them with religiously real re-experiences that supply
feelings of stability and certainty, as well as strategies for sustaining—and
perhaps enhancing—those feelings in their daily lives. By allowing visitors

This document discusses the importance and purpose of monuments and history. It provides examples of famous monuments from around the world and throughout history, and explains how monuments communicate ideas, inspire people, establish national and civic identity, and help societies remember their past. Monuments are said to be like books that educate and remind future generations of significant people, events, values, and ideas from the past. The document stresses the importance of learning from history in order to avoid past mistakes and benefit from the experiences of previous generations.
LandscapingChange Conference paper BSU29-31stMarch2016 finalJohn Robb
This document summarizes John Robb's paper on the relationship between prehistoric ritual landscapes in Wessex, England and how they are currently conserved and presented as heritage sites. It discusses how the concept of ritual landscapes has evolved in archaeology to view large territories reserved for spiritual purposes during the Neolithic and Bronze Ages, using Stonehenge and Avebury as examples. It also examines how movement through these landscapes was important for collective memory formation and how phenomenological approaches aim to understand the syntaxes and meanings encoded in their monument placements. However, some critiques argue landscape meanings and woodland changes are often unknown. The document questions how well prehistoric ritual landscapes have been incorporated into modern heritage interpretation.
During the Greek Archaic period, artists began creating more naturalistic representations of the human form, focusing on ideals of youthful male beauty. Statues of nude kouroi depicted young men with rigid frontal stances as expressions of individualism and human potential. Meanwhile, clothed korai of young women in passive poses reflected their lower status in Greek society. These developments in sculpture emerged from Greece's humanist worldview that placed humanity at the center.
This document provides an outline history of East Asia from prehistoric times to 1200 AD. It discusses the development of early civilizations in China, Korea, and Japan, highlighting that:
1) The region has been inhabited for over 200,000 years, with agriculture emerging around 10,000 BC with the domestication of millet and rice.
2) Early civilizations in East Asia were diverse, with many distinct tribal cultures rather than a single unified tradition.
3) While grain cultivation allowed for permanent settlements, people in Korea and Japan lived sustainably for millennia through foraging, fishing, and gathering before adopting rice agriculture from mainland China.

This document provides an overview of global prehistory from 30,000-500 BCE. It discusses that prehistory refers to the time before written records, and that very early art is found worldwide, not just in Europe. Homo sapiens migrated out of Africa between 120,000-50,000 years ago. The Stone Age is divided into the Paleolithic and Neolithic periods. Important artistic media, approaches, and values occurred on different continents, with Africa and Asia preceding and influencing other areas. Over time, knowledge of global prehistoric art has developed through collaboration between art historians and scientists. The function of early artistic expression is inferred based on available evidence.

1) The document discusses human evolution from a behavioral perspective, focusing on when key human behaviors like symbolic thinking, abstract thinking, and theory of mind first emerged based on the fossil and archaeological records.
2) Early humans between 2.6-2.3 mya began using stone tools and scavenging meat, suggesting problem-solving skills, but little evidence of abstract thinking, symbolic thinking, or imagined communities.
3) By around 1 mya, control of fire, new technologies, and nighttime social activities provided evidence of more advanced behaviors, though innovation remained slow.
This document discusses the origins and early history of reading. It traces the development from early humans using gestures and sounds to communicate, to the creation of symbols represented in Old Stone Age rock paintings dating back to around 50,000 BC. These rock paintings, found in places like France and Spain, typically depicted animals and hunting scenes and are considered some of the earliest forms of art and examples of abstract thinking. The progression from oral communication to symbolic representations in rock paintings helped to pave the way for the development of modern reading.
Sierra Williams: From academic blog to networked scholarly community: Lessons...Pratt_Symposium
The document summarizes lessons learned from running the LSE Impact Blog, a multi-author academic blog. It finds that blogs allow for more frequent, multimedia posts that reach a wider audience than traditional journals. However, blogging also presents challenges like the significant time commitment required, pressures around maintaining regular posts, and uncertainties around issues like commenting and copyright. Academic incentives still prioritize traditional publications over public engagement. Supporting blogging and social media use remains an ongoing challenge.

The document examines how the Roman Wall in Britain has been interpreted and presented to the public over time, from ancient writers to modern organizations like English Heritage. It discusses how authoritative interpretations can affect the physical experience of encountering the landscape and frontier.
Giles Yeo: Communicating Your Science: Lessons from the Front LinePratt_Symposium
Giles Yeo is a geneticist who studies obesity. He discusses communicating science effectively to different audiences using various mediums. Some key points he makes include: explaining the why, how, and what of scientific work; tailoring messages based on audience and medium; and simplifying concepts without being wrong. Yeo provides an example experiment where he studied how depriving cells of amino acids reduces levels of the FTO protein, which is linked to obesity.
Public humanities: from crowdsourcing to community-sourcingPratt_Symposium
This document discusses definitions and models of crowdsourcing and academic crowdsourcing projects. It defines crowdsourcing as leveraging public participation or contributions to projects. Academic crowdsourcing projects range from open recruitment with generic microtasks to focused recruitment of experts. Successful projects invite engagement from interested community members rather than relying on large anonymous groups. These projects can foster self-organizing communities that collaborate to produce quality outputs through discussion and peer review. Crowdsourcing results in communities forming around topics of interest where participants gain skills and domain knowledge.
The more things change, the more they stay the same...”: Why digital journals...Pratt_Symposium
While the fundamental needs of researchers and functions of scholarly journals have remained largely unchanged, the form of digital journals differs little from paper journals. At a macro level, journals continue to serve the needs of author mode (registration, certification, dissemination) and reader mode (identification, selection, consumption). However, at a micro level, increased formalization and rhetorical mechanisms in digital journals reflect growth in researcher populations. The conservative evolution of journals is driven by the relatively constant human and philosophical requirements for knowledge generation, occupied information ecological niches, and emphasis on efficiency over novelty in tools. Future changes may come from sustainability pressures, groupthink, or disruptive technologies, but core functions are expected to persist due to their alignment with fundamental needs.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
